Description
The Grundfos 96525458 is a genuine OEM EPDM shaft seal engineered as a direct replacement for Grundfos CRN 32, CRN 45, CRN 90, and CRN 120 series vertical multistage centrifugal pumps. Designed to maintain a reliable, leak-free seal between the rotating pump shaft and the pump housing, this component is essential to protecting pump integrity and extending service life in demanding hydronic and industrial fluid-handling applications.
EPDM (Ethylene Propylene Diene Monomer) elastomer construction makes this shaft seal an excellent choice for systems handling water, hot water, and a wide range of mildly aggressive fluids where superior temperature resistance and chemical compatibility are required. Using a genuine Grundfos replacement seal ensures proper fit, correct material compatibility, and performance consistent with original factory specifications.
